Face powder, like most makeup products, are used to mask minor imperfections visible on your skin (as Queen Elisabeth I did for smallpox scars – don’t follow her example) and to make the face skin glow. For the powder to do its job, it must have four properties: covering power, absorption, adhesiveness, and slip. Covering power can cover imperfections or blemishes and natural oil from the face. The amount of coverage needed varies from woman to woman; that’s why face powders are produced in different grades (light, medium, and heavy). Common ingredients used for it are zinc oxide, kaolin and magnesium oxide, but titanium dioxide is considered to have the best covering power.

These problems can also recur if you don’t balance the amount of oil you use. The oil must also be mixed evenly using a ribbon blender; if you don’t mix it homogeneously, there is also a risk of having oily clumps in the final pressed powder.

The particles in pressed powders are larger than the ones in loose powders. With small particles, loose powders have a fine texture and can be made in translucent or colored form. Loose powders are usually packed in jars.

If formula and pressure don’t match the godet’s size, the product won’t fit properly into the godet or will come out during application. A drop test can be performed using a drop tester to check the compaction’s quality and make sure that the contents do not easily break during the transportation of the product.
